You've found the latest firmware updater also... i couldn't find it. just only he doesn't have the 3DS version of thier card... so i hope that will not mess things up.You will need a Kernel like R4i-sdhc.hk kernel
Or might try this Kernel flashcard archive R4i-sdhc.hk
Checking out Retrofans YS-Menu
Or might running TWLmenu++ on flashcard
